The K3SX rechargeable Li-ion Polymer Battery Pack replaces the K3N battery. The K3SX uses three Samsung 18650 lithium ion for a capacity of 3000mAh. It increases the run time of the Warrior III to 70 minutes, 15 minutes longer than with older batteries. It is standard with the Warrior, Warrior III, Challenger and Innovator flashlights.
The K3SX belongs to the new generation L-Ion Polymer battery that feature a charging port next to the button switch. The charging port allows the battery to be charged without removing it from the lamp head. The charging port is protected by a fitted rubber flap when not in use.
For direct charging of the K3S battery you MUST USE a new generation K3N-AC or K3N-DC charger adapter. The K3S battery may also be charged when detached from the lamp head in the original K1-LITCC charger stand using either a K1-LITACAD 110 volt or K1-DC 12 volt car charger adapter. NOTE: The K3S battery is Center Positive and will not work with the older Center Negative flashlights.
